Komodo 3.5 features Ruby on Rails debugging as well as code intelligence capabilities such as AutoComplete and CallTips to provide as-you-type syntax checking. Also included are code colorizing, folding, automatic end statements, and smart indenting.''

A Ruby on Rails developer in Vancouver, B.C., said he favored Komodo's approach. "I like that they're focusing more on the front end, which is basically where most of the work resides in Rails," said Alex Bunardzic, technical architect at development house Jooto.

Komodo 3.5 ships for Mac OS X on Thursday, priced at US$295 for the Professional edition and $29.95 for an abbreviated Personal Edition. The Professional Edition has added features such as integration with source code control systems and a GUI builder.

The Linux and Windows version of the product ships later this year.
